i PUMP.

Application filed January 30, 1923. Serial No. 615,876.

To all 't0/0m t 'may concern.'

Be it known that I, JAMES R. MANRY, a citizen of the United States, residing at Portales, in the county of Roosevelt and Sta-te of New Mexico, have invented certain new and useful Improvements in Pumps; and I do hereby decla-re the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

T he invention relates to the type of pump embodying a wheel over which passes a chain or analogous part provided at intervals in its length with blocks which operate to displace the water in a well, when the pump is in operation.

In accordance with the present invention, the wheel is adapted to be oscillated to impart a reciprocating movement to the flexible connection provided with the blocks, a casing being provided for each end portion of the flexible connection and each casing having a foot valve for retaining the column of water therein and preventing the escape of the. same through the botto-m of the casing on the down stroke of the end portion of the flexible connection.

Other objects and advantages will be apparent and suggest themselves as the nature of the invention is understood.

While the drawings illustrate an embodi ment of the invention it is to be understood that in adapting the same to meet different conditions and requirements, various changes in the form, proportion and minor details of construction may be resorted to without departing from the nature of the invention.

Referring to the accompanying drawings forming a part of the application, y

Figure l is a front view of a pump embodying the invention,

Figure 2 is a side view thereof, parts being broken away, o p

Figure 3 is a detail view of a portion of the flexible connection to which the blocks or displacing elements are attached, andr Figure 4L is a sectional view of one of the blocks or displacement elements showing the manner of attaching the blocks or disp-lacement elements to the chain.

Corresponding and like parts are referred to in the following description and designated in the several views of the drawings by like reference characters.

blocks of the displacement element is pro- A,

vided with a longitudinal groove 5 which is deep enough to receive substantially twothirds of the chain leaving a portion thereof to extend beyond the side of the ,blocks or displacement elements, in order that the chain may bea-r against the wheel and prevent the blocks or elem-ents from becoming worn. The wells are provided with casings 6 whichare disposed in line with the opposite sides of the wheel 3 and are adapted to receive end portions of the chain or flexible connection 1l. A foot valve 7 is providedat the lower end of each of the casings 6 to confine the column of water therein. The flexible connection l including the blocks or displacement elements 5v is of su'liicient weight to submerge itself in the column of water contained in the casing and thereby displace the same, or if found more convenient sutlicient.l weights may be added to the flexible elements to causethe same to submcrge.

The'fwheel 3 has its periphery concaved, and provided with sprocket teeth 8 adapted to engage the chain l and operate the same, and the displacing elements or blocks 5 are circular in horizontal cross section and are adapted to partly lit within the concaved surface of the wheel. The casings 6 are circular in horizontal cross section and are adapted to receive the blocks or displacing elements 5.

In the practical operation of the pump, the wheel 3 is adapted to have a reverse rotary movement imparted thereto, whereby Vthe flexible connection 4 carrying the blocks or displacing elements 5 is engaged by the teeth 8 and reciprocated in the casings 6 soE as to effect a displacement of water therein, which water will be discharged at the upper end of the casing. The casings 6 are of slightly larger diameter than are the blocks or displacement elements 5, so as to provide a space between the perip-heries of the blocks or displacing elements and the inner periphery of the casing. Upon the upstrolre of the Y flexible connection carrying the blocks or displacing elements 5 in one of the casings 6, water is drawn into the casing through the foot valve 7. The opposite end of the flexible connection l moves downwardly through the column of water supported in the opposite casing by the foot valve 7, and the water in the casing in which the flexible connection is moving downwardly is prevented from escaping at Athe bottom of the casing and being displaced by the blocks 5 is forced around the blocks and between the blocks and the inner wal-ls'of the casing and discharged at the upper end of the casing. @n reverse movement rof the pump, the operation previously described is reversed and the end portion of the lflexible element which previously moved up is moved down vto displace the water in its casing 6 and discharge Y the same at the top of the casing, and the end of the flexible connection which previously moved downward and displaced the water is moved upward and draws water into its casing through the foot valve 7. It is of course to be understood that the foot valve 7 is of the one-way type. It will thus be understood that water is alternately discharged from the casings G.

'Having thus described the invention, what I claim is A pump of th'ec'haracter speeilied, oomprising a wheel, a flexible connection passing over the wheel and supported thereby, blocks provided with grooves and secured a't intervals to said flexible Vconnections, casings inline with the opposite sides of the wheel and adapted to receive end portions of the flexible connections together with the blocks, and foot valves at vthe lower ends of the casings for supporting columns of water therein.
